LITTLE SISTER, GOING THROUGH SURGERY TO DONATE BONE MARROW. TONIGHT... WLWT NEWS FIVE'S ANDREW SETTERS... SHARES THEIR AMAZING STORY. WE FIRST MET JAMESON KESSLER AND HIS SISTER SAMANTHA BACK IN JUNE WHEN THEY WERE WAITING TO GO THROUGH A BONE MARROW TRANSPLANT. YESTERDAY, IT FINALLY HAPPENED. (Kyrie Kessler) ("It was a long day, a lot of stress. We checked him in about 6 o'clock for surgery. He was really excited running around.") FOUR YEAR-OLD JAMESON DONATED HIS HEALTHY MARROW, TO HELP CURE HIS 2 YEAR-OLD SISTER SAMANTHA'S RARE BLOOD DISORDER. TWO KIDS, TWO SURGERIES, ALL IN ONE DAY. SO FAR, SO GOOD. (Kyrie Kessler) ("She had a pretty good day yesterday. There's a lot of side effects that you can have just receiving the cells and she took them all really well.") JAMESON GETS TO PLAY THE HERO, CAPE AND ALL... (Jameson Kessler, bone marrow donor) ("DO YOU KINDA FEEL LIKE A SUPER HERO BECAUSE OF THIS? Marrow Man!") IT'S NO AN EXAGGERATION TO CALL HIM A HERO. HIS PARENTS EXPLAINED TO JAMESON AND HIS OLDER SIBLINGS WHAT BEING A DONOR WOULD MEAN - IF THEY WERE LUCKY ENOUGH TO BE A MATCH. (Kyrie Kessler) ("He was the first one that was like - I'll do it. Just absolutely no fear from the beginning.") (Jameson Kessler, bone marrow donor) ("Because I had to make my sister feel better.") IF EVERYTHING GOES WELL, LITTLE SAMANTHA SHOULD MAKE A FULL RECOVERY. NO MORE MONTHLY TRANSFUSIONS, AND NO THREAT OF A DRAMATICALLY SHORTENED LIFE EXPECTANCY. SHE WILL STAY IN THE HOSPITAL FOR A WHILE LONGER, BUT JAMESON GETS TO HEAD HOME. HIS DAD SAYS HE CAN'T WAIT UNTIL HIS KIDS ARE ALL HEALTHY - AND ALL HOME. (Jeremy Kessler) ("I just want everyone to be there at the same time, is the only thing that matters to me now.) ANDREW SETTERS WLWT NEWS FIVE. THIS... IS A FAMILY OF FIGHTERS. BEFORE LITTLE SAMANTHA WAS DIAGNOSED WITH HER ILLNESS... HER FATHER BATTLED TESTICULAR CANCER.... AND WON. HE WENT THROUGH TWO SURGERIES AND CHEMO, BUT BEAT IT.
